Quick answer: On October 1, 2026, Google updated its Search Central guidance on using generative AI content. The page now states that “it is critical to manually factcheck and review all AI-generated content” before publishing, because AI systems can produce inaccuracies, also known as hallucinations. The advice covers metadata such as titles, meta descriptions, structured data and alt text, not just body copy.
What happened
Google revised its documentation titled “Google Search’s guidance on using generative AI content on your website,” last updated in October 2025. The new wording explains that generative AI models predict likely sequences of words based on their training data rather than retrieving verified facts, so their outputs can contain errors.
Google said the change brings the documentation in line with what its team has been presenting at developer events, including the Search Central Live series. Search Engine Roundtable noted that the word “critical” is rarely used in Google’s search help documents, which makes the emphasis stand out.
Why it matters
The timing is notable. The guidance arrived in the middle of the multi-wave September 2026 spam update, and in the same week Google said scaled content is now a bigger spam problem than link spam. Publishers that rely on AI for drafts, product descriptions, FAQs or SEO metadata now have explicit direction from Google: a human needs to check it.
The update also widens the scope of “content.” Many sites use AI tools to bulk-write titles, meta descriptions and image alt text. Google’s guidance makes clear those elements should be reviewed too.
